ntttcp -h

Linux Version Usage

Receiver(-r)

# -V   Verbose mode
# -r   Run as a receiver

ntttcp -r -V

Or

ntttcp

The default settings

• 5000/TCP, 5001~5016/TCP # 16 ports
• 16 threads created and run across all CPUs,
• allocating 64K receiver buffer
• run for 60 seconds

Sender(-s)

ntttcp -V -s IP

The default settings

• Server port starting at 5001/TCP
• 64 threads created and run across all CPUs
• 4 threads per each receiver port
• connections per each sender thread: 1
  connections = (16 x 4 threads x 1)
• sender socket buffer: 128K
• run for 60 seconds

Example 2(-H, -W, -t)

18:00:13 INFO: Test cycle time negotiated is: 60 seconds

Receiver

-H         # [receiver only]
            # hold receiver always running even after one test finished(可作多次測試)
            # 使用後會無視 -t 到時的 exit

ntttcp -H

Sender

-t N          # duration in seconds / negotiated time
               # 當 Sender 及 Receiver 都有會使用 -t 時, 會使用較大的 -t (Default: 60)

-W N        # Warm-up time in seconds [default: 0]

# 總測試時間: 3 + 120

ntttcp -W -t 120 -s 192.168.33.21

Example 3

Receiver

-P            # Number of ports listening on receiver side [default: 16] [max: 512]

receiver only settings

-e          # use "epoll()" instead of "select()"

./ntttcp -V -W 3 -P 64 -H -e

Sender

-P            # Number of ports listening on receiver side [default: 16] [max: 512]

Sender only settings

-n   number of threads per each receiver port        [default: 4] [max: 25600]

-l    number of connections per each sender thread [default: 1] [max: 1000]

ntttcp -V -W 3 -P 64 -n 2 -l 4 -s 192.168.33.21

# ports(-P) x threads(-n) x connections per threads(-l)
connections: 64 X 2 X 4

Other Opts

-K NIC

-p N         # Destination port number, or starting port number    [default: 5001]

sync port: 'destination port - 1/TCP' [default: 5000/TCP]

-f N         # Fixed source port number, or starting port number [default: 25001]

-u            # UDP mode (不建議使用)

mapping(-m) # Windows syntax

NumberOfReceiverPorts(Threads),Processor,ReceiverAddress(IP)

NumberOfReceiverPorts(-P): 16(default) ~ 512
Processor: *, 0, 1, etc

e.g.

ntttcp -s -m 16,*,IP

Windows Version

https://github.com/microsoft/ntttcp/

Windows Firewall
netsh advfirewall firewall add rule program=c:\tools\ntttcp.exe name="ntttcp" protocol=any dir=in action=allow enable=yes profile=ANY

 * To run throughput tests between a Windows and a Linux, 必須使用 no-sync mode

• Linux flag: -N
• Windows flag:-ns
